The most conservative estimates indicate that, by the end of 2015, the share of IPv6 traffic will reach at least 10%, and this growth will continue. A special protocol for regional registries also came into force recently. Now, a new block of IPv4 addresses will be issued only if the company proves it has already implemented IPv6. So if anyone needs a subnetwork of white IPv4 addresses, they will need to implement IPv6. This fact will also encourage the further growth of IPv6 systems and lead to an increase in traffic. As far as ordinary users are concerned, providers began appearing all over the world, issuing real IPv6-addresses to end subscribers. And so, IPv6 will be encountered more and more often, and that’s a fact we cannot ignore.
Everyone cares about their significant others' security. We all know that feeling when your calls are not answered and your Whatsapp messages not marked as read. In a moment like that you would do a lot to have any idea what is happening there. Although cell phone carriers offer geolocation services to locate another user, knowing your girlfriend is somewhere in the middle of Main Street will barely help. So what can we do about it?
Since its rise Windows was a natural habitat for all kinds of malware. Now the OS itself seems to have become one big trojan. Right after being installed it starts acting weird. The data flows in rivers to dozens of servers belonging to Microsoft and its partner companies. We will try to look into complaints of espionage manners of Windows 10 and find out what data it sneaks and where it sends it.
Code Injection is a process of injection code (often malicious) into third party application’s memory. A lot of software is using this technique: from malware to game bots. To show this approach, let’s try to execute third party application’s internal function with our own parameters, hacking simple application. Warning, C and debugger knowledge are required!
This was one of the most interesting attacks showed on Black Hat Las Vegas 2015. Let’s imagine the situation: there’s a large park of Windows computers in a large organization, and they all need to be updated. Obviously, getting all of them to download updates over the Internet is both pricy and uncomfortable. The common solution is a WSUS (Windows Server Update Services) server, which is used to manage updates. It downloads the updates and delivers them to all other computers.
The latest Nexus devices are normally the first to receive the newest Android versions. When a new firmware version is ready for release to general public, its full image is located at developers.google.com/android/nexus/images. Shortly after that, firmware starts to be distributed over the air. According to one of Google developers, Dan Morrill, (goo.gl/L85mSS), the first few OTA updates are sent to 1 % of devices. It happens at random, regardless of the location or point of sale of a phone/tablet. During this time, bugs are identified allowing the updating process to be put on hold if any critical errors are registered with a large number of users.
At first, GPUs could be used for a very narrow range of tasks (try to guess what), but they looked very attractive, and software developers decided to use their power for allocating a part of computing to graphics accelerators. Since GPU cannot be used in the same way as CPU, this required new tools that did not take long to appear. This is how originated CUDA, OpenCL and DirectCompute. The new wave was named ‘GPGPU’ (General-purpose graphics processing units) to designate the technique of using GPU for general purpose computing. As a result, people began to use a number of completely different microprocessors to solve some very common tasks. This gave rise to the term “heterogeneous parallelism”, which is actually the topic of our today’s discussion.
